Eisenstein Hecke algebras and conjectures in Iwasawa theory

Abstract: Abstract. We formulate a weak Gorenstein property for the Eisenstein component of the p-adic Hecke algebra associated to modular forms. We show that this weak Gorenstein property holds if and only if a weak form of Sharifi's conjecture and a weak form of Greenberg's conjecture hold.

“…But by the previous lemma, Fitt Λ (I/I 2 ) ⊂ (ξ) = char Λ (X χ (1)). This implies that the ker(Θ) is finite (see [Wak15a,Lem. A.7] for example), and hence ker(Θ) = 0, since X χ (1) has no finite submodule by Ferrero-Washington [FW79].…”
